To all whom it may concern.'

Be it known that I, HOWARD O. MCMIL- LAN, a citizen of the UnitedStates, residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in Shoreand Trench Braces; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will .enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to a timber support or shore such as commonlyused in building construction. It is desirable to have a shore whichfirmly supports and holds the timber' vand it is very desirable to havea shore which can be adjusted so that the timber supporting part can beraised any distance desired relatively to the standard.

.It is an object of this invention, therefore, to provide a shorecomprising a standard and a timber supporting member movable relativelythereto, together with means for moving said timber supporting memberany distance desired along the standard, which shore also has a highdegree of utility when used as a trench brace.

It is a further object of the invention to provide ashore, as set forthin the preceding paragraph,`in which the standard also has meansadjacent its top for4 clamping the supported' timber.

It is still another object of the invention to-provide a shore havin astandard with a timber supporting brac et slidable thereon, togetherwith means adapted to pass transversely through the bracket and standardfor raising and holding said bracket in the desired position. j

It is still another object ofthe invention to provide a shore, as setforth in the preceding paragraph, in which the standard has V a seriesof spaced slots therein and said bracket has a plurality of slots.therethrough spaced a different distance apart than the slots in saidstandard, said 'means comprisv ing a pair of wedges adaptedto be ldriventhrough the slots in said bracket 'and standard and relatively move saidparts.

These and other ob'ects and advantages of the invention willv efully'setforth in ythe following description made in connection with theaccompanying drawings in which like reference characters refer to thesame parts throughout the diierent views,'

and in which,

Fig.'2 1s a view in side elevation, as seen from the right of Fig.1';

Fig. 3 is a top plan view of the device Fig. 4 is a transverse sectionon the line 4 1 of Fig.'2 as indicated by the arrows;

Fig. 52 is a view similar to Fig. 3, showing a modification; and

Fig. 64 is a view in side elevation of Fig. 5. 'Referring to thedrawings, a shore is shown comprising av standard 5. While this standardmay be made ofv various forms, or shapes, in the lembodiment of theinvention illustrated, the same is shown as formed of a T-bar having alower end extending substantially at right angles. to its `length towhich is connected a foot 5"' compri'sin a flat platehaving upstandingears 5b em racing the main arm or web 5c of the 'standard 5 and beingvconnected thereto by a suitable rivet, one side of the ears 5h beingdisposed ad'- jacent the cross arms 5d of the standard. A.

timber supporting bracket 6 is'provided having a main portion with aT-shaped slot 6'L therein adapted to fit over the standard 5 lso thatthe bracket is slidable thereon and has Iflat sides embracing the mainarm or web 5c'of the standard.' The bracket 6 has a plate 6b extendingoutwardly of its top substantially at right angles to the face vof thecrossarms 5d of the standard, which plate hasan upwardly projecting fin6c at its outer edge. A central triangular rib 6 is shown-as connectingthe plate 6b to themain portion of the bracket and said vplate 6" has aplurality of hole-s .6 therethrough adaptedto receive nails or spikes7-driven therethrough upwardly into the bottoni of the timber 9 which issupported upon plate 6". The main web 5" of the standard 5' is providedwith a plurality of elonvated spaced slots 5 extending therethrough sown as rectangular in shape and alined longitudinally of said standard.The sides-of bracket 6 at each side 'of web '5c are provided with aplurality of similarly shaped slots 6 cen-` 'trally alined with theslots buty spaced a different distance apart than' the slots 5. In theembodiment of the invention illustrated, theslots 6t are shown as s.aced farther apart .than the slots 5. A pair of wedges 8' are providedadapted to extend through the slots 5e and 6', as clearly shown in-Figs.1, 2 and 4, said wedges being shown as having small i square apertures 8extending therethrough 'wrenches to turn said screws.

adjacent their longer ends. Pairs of lugs 6 and 6g are provided at oneside of brackets 6 between which wedges 8 move, the lugs Gf beingthreaded to receive set screws 12. The holes 8a are made to lit overtheheads of screws 12 so that the wedges'8 constitute The standard i hassecured thereto adjacent its top, a yoke 10 andwhile'this yoke may bevariously formed, in the embodiment of the invention illustrated, it isshown as formed of a flat bar havingits ends disposed at eachl side ofweb 5c and riveted thereto, the sides of said yoke extending outwardlyat each side' ot said web closely. adjacent the cross arms 5" andparallel to and bevond the latter. The

sides of the yoke are then extended outwardly parallel to each other andat right angles to the front of the standard 5, the sides being joinedby an end portion l()n extending at Aan acute angle to said sides. Thesides of theY yoke 10 "adjacent the end 10 are provided ...with alinedelongated slots 10b adapted to re- In the modification shown in Fig. 6 adifferent form of yoke is shown to be used inl place of yoke 10. Anglepieces 13 are provided villustrated as made from a short piece of flatbar bent at right angles, said members .being'disposed against oppositesides of web 5p and riveted thereto sof that the bent portionsprojectoutwardly and oppositely at right angles to said web. Strips orplates 14 and l15 also made from flat bars are riveted at either side ofthe members 13 and project forwardly at both sides of the front of thestandard 5, plates 14 and 15 being secured at their outer ends; to astrip or plate 16 riveted between the plates 14 and extending to andrivetedl between the vplates 15, said plates 16 extending. at an angleto the front face of standard 5. The plates 14 and 15 also extend ateach side of the timber 9 and the wedge 11 can be driven into placebetween plates 14' and 1'5 and with its inclined side enga ing the edgeof plate l6.` The other sideo the wedge 11 engages the tace ot timber 9so that said timber is tightlydclamped in position against the standar5. n In the use of the device asa shore the same will be broughtadjacent the timber 9l to be supported and the flat bottom end of saidtimber will be engaged with the'l top yof plate 6b, the timber beingdisposed within and held from outward movement at its lower end by thetin 6. The timber can be held against lateral movement by driving thespikes 7 into the bottom thereof through the holes 6e. It isunnecessary, therefore, to lit the bottom ofthe timber between any partsor flanges at its sides. `The timber 9 -will pass through the yoke 10.In order to support the bracket 6, one of the wedges 8 will pass througha pair of slots 6t in the bracket and through one of the slots 5c in thestandard. If it is desired to raise the timber 9 the wedge 8 will bedriven through the bracket 6 and web 5c of lthe standard j and thesuccessive movements of the wedge resulting from the blows thereon willgradually raise the bracket 6 and timber 9. When j the wedge 8 has beendriven in place to" its widest part, another slot 5c will be broughtinto partial alinement with the other pair of slots 6t and the otherwedge 8 can then be inserted through these partially alined slotsanddriven through the brackets and standard. The brackety 6 will be raisedas this wedge is successively driven intol place and when the wide partof the wedge has been driven into the bracket 6 another slot 5 will bepartially brought into alinement with the lirst mentioned pair ot slotsGf so that the wedge iirst used can again be inserted and -driven intoplace. It is thus possible by the successive use of the wedges 8 toraise the bracket 6 and move the same along the standard 5 any desireddistance, The bracket 6 can be moved throughout substantially the wholelength of the standard 5. The bracket 6 can'be raised with the :rod ortimber 9 thereon and it is unnecessary to make any adjustment of thebracket 6 and standard 5 4or to change the relative position beforeusing the next wedge 8. The bracket 6 can be continuously moved by thesuccessive use of the wedges without any retrograde movement ot thebracket 6. The wedges 8 not only act to raise the bracket means but alsoform a holding means for holding the same in desired position. While thewedges 8 bind against the ends of slots in bracket 8 and web 5, and aresecurely held in place, the set screws 12 are provided by means of whichthe wedges can be securely locked in position, if desired. The setscrews 12 can readily be turned by using one of the wedges 8 as awrench. After the timber 9 is brought to the desired position, the wedge11 is inserted into slots 10b with its inclined side in engagement `withthe inclined end 10l of the yoke 10 and the wedge then driven tightlyinto position. The wedge 11 will act to irmly clamp the timber 9 betweenthe same and the front of standard 5 so that'the tim'- ber isheld verysecurely in position. The timber does not have to be dressed to exactlyfit the yoke. Pins 11b and tongues 11c prevent the wedges 11 from beingremoved lool"A The 'operation of form of oke shown in Fig. 5 is Vsimilarto that of yo e 10 and it is thought .no further description thereofwill be necessary.

When the device is used as a trench brace the saine will extendtransversely across the trench at right an les to the sides thereof, thebrace 5% will e placedviat against a board 'at one side of the trench. Ablock similar to the short length ofA the timber 9 illustrated will nowbe placed through the yoke 10 and against the plate 6", said block beingof sulicient length to extend beyond the yoke 10. The outer end yof thisblock can now be engaged with a board at the lside of the trenchopposite that at whiclithe brace 52L is disposed. The block can then bemoved by the bracket 6 by the use of the wedges, as above described. Thesides of the trench can thus be effectively braced and the boards at theside of the trench can be pressed apart asis desired.

From the above' description it is seen that applicant has provided avery simple and efficient adjustable shore and trenchv brace. When usedas ashore, the device, as described, can be easily and quickly laced inposition and the timber supporte out any re-setting of the bracket 6.The

device is easily and inexpensively made and can be made very rugged sothat it will be quite durable.

It will, of course, be understood," that various changes may be made inthe form, details, arrangement and proportions of the parts withoutdeparting from the scope of applicants invention, which, generallystated, consists in a device capable of carrying out the objectsNaboveset forth, in the novel parts and combinations of parts disclosed anddefined in the appended claims. v What is claimed is: v
